.....I know it's not a mozzy .....
we'll forgive you...... this time
being such a short board the glass that's delaminated wont be a huge issue strength wise
so really they probably just need sealing up
Don't use varnish, sure its easy and quick and looks good but you'll pay for it the next time the maintance schedule comes around... check TwiceShy's thread and the varnish on the rudder blades and centreboards..... took a full day to remove the varnish and polish up the glass to a usable finish for each piece.... 4 wasted days because of the varnish
the other negative for varnish is future repairs, if at some stage you need to fix an issue you'll find that varnish and resin don't play well together.
So the answer your chasing in my opinion would be the epiglass-everdure treatment..... little bit more effort now but you'll appreciate it further down the track
download this and print it out..... & store with the tin
